State Of The Climate - American Meterological Society

An international, peer-reviewed publication released each summer, the State of the Climate is the authoritative annual summary of the global climate published as a supplement to the Bulletin of the American Meteorological Society. The report, compiled by NOAA’s Center for Weather and Climate at the National Centers for Environmental Information is based on contributions from scientists from around the world. It provides a detailed update on global climate indicators, notable weather events, and other data collected by environmental monitoring stations and instruments located on land, water, ice, and in space.

Here are some highlights - the first paragraph from the chapter titled "Global Climate":

Following the warmest year on record in 2014
according to most estimates, 2015 reached record
warmth yet again, surpassing the previous record
by more than 0.1°C. The considerable warmth,
protracted strong El Niño, and new record levels of
greenhouse gases provided climatological highlights
for the year.

And:

Atmospheric burdens of the three dominant
greenhouse gases (CO2, CH
4, N2O) all continued to
increase during 2015. The annual average CO2 mole
fraction at Mauna Loa, Hawaii (MLO), exceeded
400 ppm, a milestone never before surpassed in the
MLO record or in measurements of air trapped in
ice cores for up to 800,000 years.
